SPINACI-I, ETC., WASHING MACHINE Application filed April 14, 1930. Serial No. 444,306.

My invention relates to a machine of the cavities thereof being designated 15. Regeneral character disclosed in Letters Patent movably surmounting the wall 11 is a cylinof the United States issued to me on March der or chamber member 16 which also is 25, 1980, for agitating etc. machines, Nos. preferably a single metallic casting. 1,752,202 and 1,7 52,203. rThe cylinder 16 forms a chamber in which 55 An important aim of the present invention the spinach, other leafy vegetables or the is to provide a machine of such construction equivalent are received, agitated and washed. that will effectively wash or agitate spinach, Such cylinder 16 is thickened at its lower other leafy vegetables or the equivalent, that edge which provides a shoulder 17 to rest can be manufactured at minimum cost and is on the wall 11, an annular depending flange 6b exceedingly durable, and which enables me 18 inwardly thereof and telescoping into to use an agitator having arms which are rabowl 10 and a shoulder 19 in line with shouldially straight. der 17 but on the opposite sideof said flange Another object is to provide a construction 18.

Such blades 32 are radially straight and preferably of the same width throughout and their end edges as shown in Figure 1 are preferably inclined to closely conform to the inner surface of the iange 2'? and the portion 28. ln addition, the blades are of a height to overlap or extend bot-h above and below the junction line occurring at the shoulder 19 which rests on the wall 17, to keep all materials agitated and prevent their lodging between the wall 27 and said shoulder 19. Said blades 32 may be flat as shown in Figure 3 but if preferred they may be dished or concave as at 33, as shown in Figure 4, the other equivalent parts having primed reference characters. Such an agitator l find lvery eflicient in the washing of spinach or the equivalent and exceedingly durable-and capable of manufacture at very low cost.

The drive shaft 22 may be driven in any suitable manner and for instance by the mechanism disclosed in my copending application Serial No. 429,156, filed February 17, 1930.

Simultaneously with operation of the agitator, water preferably continuously flows from any desired source through a nozzle 34 under control of a valve 85, into chamber 16, such water and foreign matter discharging or draining through a pipe 36 coupled to the cylinder.

Aside from the agitator and the disk 23, certain details of the parts may be considered as divided out of the application for the aforesaid Patent 1,7 52,202.

Presuming operation of the machine, water continuously iiows through nozzle 34 into the cylinder and onto and through the spinach or equivalent material therein, such material being supported by the disk 23. At the same time, the agitator 25 through its radially straight blades 32 produces the necessary centrifugal and centripetal motion to move the spinach for thorough washing or cleansing thereof, the water and foreign matter. escaping through the perforations of the disk, the particular construction especially enabling the escape of the water and foreign matter through t-he side of the disk as at the wall 27.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim:

1. A machine of the class described having a cylinder, a bowl-shaped base for said cylinder, a disk to support material in said cylinder to be washed, said disk having a marginal perforated wall inclined and spaced from the adjacent p ortion of the cylinder, said disk being overlapped by said cylinder, said cylinder and base being separable to enable operative positioning of the disk, and

an agitator movable over said disk to cause discharge through the marginal perforated wall.

2. A machine of the class 'described having a cylinder, a bowl-shaped base for said cylinder, a perforated disk to support material in said cylinder to be washed, said cylinder and disk having side wall surfaces substantially angularly disposed and merging with each other, the side wall of said disk being perforated, said disk being overlapped by said cylinder, said cylinder and base being separable whereby the disk may be operatively positioned, and an agitator movable over the disk.

3. A machine of the class described having a cylinder, a bowl-shaped base for said cylinder, a perforated disk in said base to support material to be washed, said cylinder and disk having side wall surfaces substantially angularly disposed and merging with each other, the side wall of said disk being perforated, and an agitator movable over the disk, and blades on said agitator whose end walls substantially conform to the angle of said surfaces.

4. A machine of the class described having a cylinder member, a bowl-shaped base member therefor, a disk in one of said members to support material to be washed and permit drainage of water therefrom at the bottom and at the side wall into the bowl-shaped base, the side wall of the disk being perforated and inclined upwardly and outwardly, the adjacent wall surface of the cylinder being similarly inclined, said side wall below its top being spaced from the side wall of the cylinder, said disk being overlapped by said cylinder, said cylinder and base being separable whereby the disk may be operatively positioned, and an agitator movable over said disk.

5. A machine of the class described having a cylinder member, a bowl-shaped base member therefor, a disk in one of said members to support material to be washed and permit drainage of water therefrom' into the bowlshaped base, the side wall of the disk being perforated and inclined upwardly and outwardly, the adjacent wall surface of the cylinder being similarly inclined, said side Wall below its top being spaced from the side wall of the cylinder, and an agitator movable over said disk, the free end walls of the blades of the agitator being inclined substantially in conformity with the inclination of said side wall.

6. A machine of the class described having a. cylinder member, a bowl-shaped base member therefor, a disk in one of said members to support material to be washed and permit drainage of water therefrom into the bowlshaped base, the side wall of the disk being perforated and inclined upwardly and outwardly, the adj acentwallsurface of the cylinder being similarly inclined, said side wall below its top being spaced from the side wall of the cylinder, and an agitator movable over said disk, said agitator having substantially radially straight blades extending above and below the top of said side wall, and the free end walls of the blades being inclined substantially in conformity with the inclination of said side wall.

7. A machine of the class described having a cylinder, a bowl-shaped base for said cylinder, a disk to support material in said cylinder to be washed, said disk having a marginal perforated wall overlapped by the cyl inder and spaced from the adjacent portion of the bowl, said base and cylinder being separable, and an agitator movable over said disk to cause discharge through the marginal perforated wall.

In testimony whereof I have aiixed my signature.
